I am finally putting on new brake lines, and while I'm at it I'm putting Speed Bleeders in the wheel cylinders. I bought all the wheel cylinders as a set from LMC Truck, the two in the rear matched, looked identical to each other and the replacements, both were the same part number, same manufacturer etc. I found out last night that the bleeder screws were different sizes. Both the front and the LR wheels have a larger size thread that is the same size as the Speed Bleeders I ordered. The RR wheel, though, has a smaller thread that the new bleeders won't fit. My question is this: Is it likely that its the wrong cylinder altogether, or is it more likely that it just has a different bleeder screw for some reason (older manufacture, different plant, different brand rebuilt somewhere along the line etc.) If its not gonna be a safety issue, I will leave that one in place and either just use the stock bleeder or get a different Speed Bleeder for it rather than tear the brakes apart and buy a new cylinder. But being brakes, and especially since its for my son to drive, I don't want to leave it if there are potential safety issues. Any input?
I would think that as long as the Cyl/piston diameter is the same you shouldn't have any problems. Personally I would TRY to match it to the others, just cause little **** like that bugs me knowing its there
if you have access to a lathe you can do what i did, or if your talented enough you could use a drill press, i took a speed bleeder i had and made an adapter out of br***, now i can just keep my normal bleeders and attach my universal speed bleeder with a short piece of hose, its the last speed bleeder i ever need to buy.
Could be different manufacturer, I've seen this before. With the 'worldwide ecomomy', everything today comes from the cheapest place.
I think I'll just run it then, gonna get a different speed bleeder for it. I'm kinds like Iceberg, it bugs me that it doesn't match, but how often are you gonna actually look at the bleeders anyway? I'll **** it up and drive on...
